[asterisk-users] IAX2 getting stuck

[Kseniya Blashchuk]

Hmmm.. So if you are sure that the poke packets leave the network interface
(I would still check with tcpdump as well, maybe a firewall issue?) then it
makes sense to check the other side to make sure the poke packets reach
other servers.
I mean with tcpdump you may see if there are incoming packets from your
peers on the interface. If there are, then they are dropped or ignored by
your servers. If no, then it's better to check the other side.
you may try smth like 'tcpdump -npi <ethN> host <your peer> and port 4569'
Do you have a firewall configured on this server?
